Linux里面能够在命令行里造成对话框，用光标上下，左右选择，一屏一屏的问答选择，填写。shell

whiptail是Linux不须要另行安装，默认就有的，其它的好比dialog须要另行安装，很麻烦，虽然功能比较好些。bash

帖一个写好的东西。ide

#!/bin/bash

trap "" 2

while true

do

OPTION=$(whiptail --title "Email Manager" --nocancel --menu "Choose your option" 15 60 4 \

"1" "Add Email User" \

"2" "Delete Email User" \

"3" "List Email User" \

"4" "EXIT"  3>&1 1>&2 2>&3)

case $OPTION in

1)

EmailAddress=$(whiptail --title "EmailAddress-form Input Box" --inputbox "What is your add EmailAddress?" 10 60 @shenxu.com 3>&1 1>&2 2>&3)

exitstatus=$?

if [ $exitstatus = 0 ]; then

grep $EmailAddress /etc/postfix/virtual_mailbox_maps>/dev/nul

exitstatus=$?

if [ $exitstatus = 0 ]; then

whiptail --msgbox "The Email Address is a existed" 10 40

elif (whiptail --title "Add Yes/No Box" --yesno "Are you sure add $EmailAddress." 10 60) then

/etc/postfix/mailadd.sh $EmailAddress

whiptail --msgbox "The Email Address $EmailAddress is a added." 10 40

fi

else

whiptail --msgbox "You chose Cancel." 10 40

fi

;;

2)

EmailAddress=$(whiptail --title "EmailAddress-form Input Box" --inputbox "What is your Delete EmailAddress?" 10 60 @shenxu.com 3>&1 1>&2 2>&3)

exitstatus=$?

if [ $exitstatus = 0 ]; then

grep $EmailAddress /etc/postfix/virtual_mailbox_maps>/dev/nul

exitstatus=$?

if [ $exitstatus != 0 ]; then

whiptail --msgbox "The Email Address $EmailAddress is a not exist." 10 40

elif (whiptail --title "Add Yes/No Box" --yesno "Are you sure delete $EmailAddress." 10 60) then

/etc/postfix/maildel.sh $EmailAddress

whiptail --msgbox "The Email Address $EmailAddress is a deleted." 10 40

fi

else

whiptail --msgbox "You chose Cancel." 10 40

fi

;;

3)

EmailAddress=$(cat /etc/postfix/virtual_mailbox_maps | awk '{print $1}')

whiptail --msgbox "The Email User list are $EmailAddress." --scrolltext 20 40

;;

4)

echo "EXIT"

break

;;

esac

done

trap : 2post

whiptail --title "Email Manager" --nocancel --menu "Choose your option" 15 60 4 \

"1" "Add Email User" \

"2" "Delete Email User" \

"3" "List Email User" \

"4" "EXIT"  3>&1 1>&2 2>&3命令行

--title "Email Manager" 是标题，双引号里是本身填的提示信息orm

--nocancel 是在这个图文里面不显示取消，只显示OKip

--menu "Choose your option" 15 60 4 是表示菜单提示，双引号里是本身填的提示信息，15是高度，60是长度，4是有个选择项目input

下面的1-4是本身的提示it

最后比较关键，3>&1 1>&2 2>&3是为了把选择的内容填进变量OPTIONio

whiptail --title "EmailAddress-form Input Box" --inputbox "What is your add EmailAddress?" 10 60 @shenxu.com 3>&1 1>&2 2>&3

--inputbox "What is your add EmailAddress?" 是能够造成一个让用户输入的提示框

@shenxu.com 是默认输入text里的值

whiptail --msgbox "You chose Cancel." 10 40 是显示一行你的提示

其实还有--infobox，彷佛和msgbox很像，其实不一样，它基本上用不上，是在shell运行完后，能够往前翻页能看见的东西

--scrolltext 20 40是为了显示多行的时候能够上下滚动

另外还有--passwordbox和text同样输入，就是以***显示

whiptail --checklist "choose" 15 60 2 "1" "aa" ON "2" "bb" ON

15 60仍是高和宽，2是有几个选项，和menu同样，后面多了一个ON或者OFF表示状态，就是菜单出来后默认是否是选，On是选，OFF不选，用空格键来选择。能够多选。

--radiolist，不能够多选了。ON就只能有一个，其它必须是OFF

还有一个显示进度条的--gauge，我以为没啥用处。

#!/bin/bash

{

for n in `seq 100`

do

sleep 1

echo $n

done

} | whiptail --gauge "Please wait while installing" 6 60 0
